GEORGE E. JACKSON, OF NEWTON, IOWA.

BALING-PR'ESS.

To all whom 'it may concern:

Be it known that I, GEORGE E. JACKSON, citizen of the United States,residing at Newton, in the county of Jasper and State of Iowa, haveinvented certain new and useful Improvements in Ealing-Presses, of whichthe following is a specification.

This invention comprehends certain new and useful improvements inpresses for baling hay or similar materials.

One of the primary objects of the invention is a baling press in whichthe parts are so arranged that the plunger will have a relatively quickreturn motion and a slow forward motion so as to leave the feed openingof the press open for a comparatively long time, thereby giving thepacking fork or feeder more time to operate, and whereby also there willbe a maximum power at the compressing end of the stroke of the plunger,which is the time when the greatest pressure is required, the load beingevenly distributed all over the machine and avoiding any undue strainupon the gearing, and also thereby permitting relatively light gears tobe employed.

The invention also has for its object a combined twister and wire cutterwhich will operate effectively to twist the strands of wire tightlyaround the bale and subsequently cut the wire and permit a portionthereof to pass out with the bale, and also a combined wire holder anddrum, of novel and useful construction for carrying away the waste wire,the said wire holder and drum embodying positive actuating mechanismwhich operates intermittently to carry off this waste wire and securelyhold one end of the wire as the bale is being formed.

A further object of the invention is an improved construction of needleswhich are carried by the plunger or ram of the press, and which arecombined with novel actuating mechanism whereby the wires may be quicklycarried upwardly around the rear side of the bale and into the twisters,the needles being so arranged that near the limit of the stroke of theplunger in compressing the hay or the like the needles will yield andpermit the plunger to have a slight independent movement in a forwarddirection so as to effect the nal compression while the needles remainrelatively stationary and the twisters operate to twist the wire aroundthe bale. And a further object of the invention is a baling press whichwill be com- Specification of Letters Patent.

paratively light and yet strong and durable and which will be composedof comparatively few parts that may be easily manufactured and readilyassembled, and which will operate eiciently and automatically vin allthe necessary steps, after the wires have once been threaded through theneedles and secured to the combined wire holders and drums for carryingaway the waste wire.

Vith these and other objects in view as will more fully appear as thedescription proceeds, the invention consists in certain constructions,arrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention reference is to be had to thefollowing description and accompanying drawings in which:

Figure 1 is top plan view of one portion of a baling press constructedin accordance with my invention; Fig. l1L is a similar View of anotherportion of the press and the main driving gears; Fig. 2 is a sideelevation of a portion of the press parts being shown in section: Fig.21 is a side elevation of the rear end of the press. Fig. 3 is a detailside view of a part of the mechanism for actuating the needles, or wirecarriers: Figs. 4 and 5 are detail sectional views of a portion of theneedles showing the pivoted fingers thereof; in different positions inthese two views respectively; Figs. 6 and 7 are detail top plan and edgeviews of one of the wire twisters and cutters; Figs. 8 and 9 are similarviews of another' form of cutting mechanism; and, Fig. 10 is atransverse sectional View on an enlarged scale, the section being takensubstantially on the line 10-10 of Fig. 1 looking in the direction ofthe arrows; and, Figs. ll and l2 are longitudinal sectional viewsthrough the baling chamber illustrating the wire carrying needles indifferent positions respectively. y

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The framework of my improved baling press may be of any desiredconstruction and design, and is preferably mounted upon traveling wheels(not shown) so that it may be moved conveniently from place to placewherever it is desired that the baling operation shall be performed.Near the rear end of the framework the driving shaft 1 is journaled,said shaft 'carrying at one end a driving pulley 2 by which it mayreceive its motion from any suitable source of power, and carrying atits other end a spur pinion 3 which meshes with a relatively large spurgear wheel 4 on one end of a countersh'aft 5. The said counter shaftcarries at its o-pposite end a spur pinion 6, which meshes with a gearWheel 7 on one endof a transverse shaft 8, the said last named shaftcarrying scroll gears 9 which meshV with corresponding gears 10 carriedby stub shafts 11. The scroll gears 10 are provided with a double crank12 to which one end of a pitman 13 is connected, the opposite end of thepitman having a jointed connection with the plunger or ram 14. By thevarrangement of scroll gears herein shown and described, it is obviousthat the plunger will have a relatively slow forward -1notion, and aquicker return movement.

In the present proportion of parts, the return' stroke is completed in130O of a revol'ution of the scroll gears 9 and the balingV strokefin230, the gain thus effected being used on the baling stroke, and thequick return leaving the opening of the press clear for a maximum amountof time so as to give the packing fork (not shown) and other l wardly asbest seen in Fig. l to one side of the press, the said shaft carrying atits projecting end a crank 16 on which a roller 17 is mounted. Thisroller 17 is designed to travel on a cam track 18, the said track beingymounted for an up and down movement in'guide channels 19 secured to oneside of the press-'framework as best illustrated in Figs; l, 2 and 3. Inorder to effect the requisite vertical movement'of the track 18 so as-tocarry its entrance end into and out of alinement With the roller 17, Ihave provided bell cranks 20 and 21 which are connected to the track bylinks 22 and connectedto each other by a link 23. The

@downwardly extending arm of the bell crank 21 is connected, by means ofa rod 24, to a crank disk 25 mounted on one end of a shaft 26. Ihe saidshaft 26 carries a loose pinion 27 designed to be actuated by jamutilated gear or spaced segments 23 mounted on one end of the shaft 8,the pinion 27 being coupled to its shaft 26 by means of a clutch 29.Hence as the disk 25 is rotated, it is obvious that the connecting wrod24 will be moved in a direction to raise the track 18 at the correcttime sol that as the plunger moves forwardly, the roller 17 on the crank16 will engage the track 1S imparting a partial revolution to the shaft18.

The shaft 15 carries a segment 30 which meshes with a pinion 31 on theneedle carrying shaft 32, the latter being journaled in the ram orplunger 14. Hence as the shaft 15 is turned as before described, theshaft 32 will also be given a partial rotation in a drection to carrythe needles from a lowered inoperative position to an upper operativeposition so as to carry the wires upwardly over the rear end of the baleand to the twisting mechanism as presently described.

It is to be particularly noted that the needles designated 33 aremounted on their shaft 32 at a point to one Side of the middle of theneedles, so that when the needles are in lowered position, they will notproject above the frame work of the press, but when they are swungaround to an o erative position they will project, as il ustrated indotted lines in Fig. 2, and in full lines in Fig. 12, and will be in aproper position to carry the wires into the-twisting mechanism.

T he wires designated 34 are fed from spools designated 35 journaled inhangers 36 depending from the press framework and are carried forwardlythrough guides 37 on the plunger 14 and also through eyes 38 formed insaid plunger. They Vare then passed forwardly over rollers 39 carried bythe then downwardly rojecting ends of the needles 33 and secure to thewire holders hereinafter more specifically described. As the needles areswung around to the dotted line position illustrated in Fifr. 2, by themeans hereinbefore set forth, 1t is evident that the wires 34 will becarried upwardly along the rear side of the bale and loo s will beformed in the wires as illustrated y the dotted lines in Fig. 2.

Each needle 33 carries at one end a pivoted finger 40 (see Figs. 4 and5) spring pressed to the position illustrated in Fig. 4 and each finger40 is formed with two notches or recesses designated 41 and 42. When theneedles are being moved from their lowered position illustrated in Fig.2

to the operative position projecting above the framework of the press asillustrated in dotted lines in such view, and in full lines in Fig. 12,the wire will first lie in the notch or recess 41, but as the needlesare continued in their upward movement it is obvious that the finger 40will yield to permit that portion of the wire 34 which has been carriedin the recess 41 to pass rearwardly and form the return portion of theloop, as indicated in Fig. 5, while the other portion of the loop willlie in the recess 42 as also indicated in Fig. 5, and in dotted lines inFig. 2. Each needle 33 is formed with stop lugs 40a between which thefingers 40 are mounted, whereby to limit the movement of the stop lugsin both directions, as clearly illustrated in Figs. 4 and 5. Now as thecam track 18 is raised and the plunger is moved forwardly and theneedles swung around to an upward operative position, the wire will becarried to the twisting mechanism, when the plunger finally arrives atthe baling end of the stroke, while on the return stroke the cam track18 will force the crank 16 to reverse its movement so as to return theneedles to their first or lowered inoperative position and the crankdisk 25 will then be given the second one of its two one-halfrevolutions, so as to lower the track 18 below the roller 17, to permitthe plunger to compress the material until the next bale is formed.

While the ram is at the baling end of its stroke with the needles up andthe wires in the twisters 44, the twisters are rotated. In the presentembodiment of the invention, these twisters are in the form of spurpinions, each with a radial slot 45 for the entrance of the two strandsof wire to be twisted together, said slot being of a size to permit twowires to enter one after the other and preventing any passing of thewires in the slotand hence insuring that the wires will be twisted whenthe twisters are rotated. The twisters 44 are journaled in suitablebearings, on a portion of the press framework and their spur teeth meshwith corresponding teeth on the relatively large spur gears 46. Thesegears 46 are fast with bevel gears 47 which mesh with verticallydisposed bevel gears 48, on a transversely extending shaft 49. Thisshaft 49 carries a bevel pinion 50 at one end, said pinion meshing witha corresponding pinion 51 on one end of an obliquely disposed shaft 52extending substantially the full length of the press frameworkdownwardly to the rear end thereof, as best illustrated in Figs. 1, 1aand is provided at its rear end with a bevel pinion 53. This last namedpinion meshes with a bevel pinion 5.4 on a shaft 55 which is journaledin the press framework in substantially transverse alinement with theshaft 26 before mentioned. The shaft 55 carries a loose pinion 56 whichmeshes with a mutilated gear or toothed segment 57 mounted on the beforementioned shaft 8. The loose pinion 56 is designed to be coupled withits shaft 55 by means of a clutch 58. It is intended that the clutches29 and 58 be automatically set in operation when a requisite amount ofhay or other material has been admitted into the press and I prefer forthe automatic operation of the clutches 29 and 58, the automaticmeasuring mechanism described and claimed in Letters Patent of theUnited States #919,585 issued to me April 27, 1909. As this automaticmechanism is fully disclosed in said patent, it is not deemed necessaryto again describe it here, particularly as other forms of clutchactuating means may be employed if desired so far as the presentinvention is concerned.

Returning now to the construction and operation of the twisters 44', itis to be understood that the twisters will be rotated as soon as thewires have been carried forwardly into the slots 45 by the needles 33.At the completion of the twisting operation the wires are cut 0H. Oneform of the cutting mechanism is illustrated in Figs. 6 and 7. The samecomprises blades 59 carried by the respective gear wheels 46 each bladebeing arranged to sweep in a horizontal plane underneath a knife bar 60secured to some stationary portion of the framework and over a cuttingsurface 61 which is in the form of a boss constituting an integral hubportion of the twister 44. Another form of cutting mechanism isillustrated in Figs. 8 and 9. In this modification, each twister 44carries a laterally movable cutter 612L arranged to be swept across theslot 45 and spring pressed to an inoperative position as shown, saidcutter being actuated by means of a cam 62 carried by the gear wheel 46.

Prior to the initial operation of the press the wires 34 are threaded byhand through the guides 37 and eyes 38 and are carried upwardly andgiven several turns around the wire holders and waste wire drums 63.These wire holders and waste wire drums 63 are mounted on a.transversely extending shaft 64 and occupy positions directly above therespective twisters 44. The wires after they are carried forwardly fromthe drums 63 are passed over pulleys 65 and then weights 66 are hung onthem so as to prevent the wires from slipping on the peripheries of thedrums. On the shaft 64 a disk 67 is mounted. This disk is formed withthree sets of teeth 68 and intervening concave cam surfaces 69, thelatter being arranged to engage with the periphery of an actuating disk70 secured on the shaft 49. The disk 70 is provided with one set ofteeth 71 designed to intermittently engage with one of the sets of teeth68 at each revo- -lution of the shaft 49 so as to impart an intermittentmovement to the drums 63 in a direction to take up the twisted portionof the wires and carry the waste wire in a foi ward direction away fromthe press. It is clear that a portion of the wire after being cut offmoves out with the bale, and these drums 63 will hold the remainingparts of the wire so that as the needles are moved downwardly, the wireswill lie across th-e bed vof the press underneath the material which issubsequently fed in preparatory to forming the next bale.

In order to permit the needles to yield while at the same timepermitting the plunger to have a slight independent movement 3 Ofi atvthe completion of its forward stroke, springs 72"are mounted in socketsin the plunger and bear against the rear edges of the-needles when thelatter are in their raised or operative position.

From the foregoing description in connectiony with the accompanyingdrawings, it is believed that the practical operation of my improvedbaling press isV obvious. After the wires have been threaded through theguides 37 and eyes 38 as before described, and engaged with the wireholders and drums 63 as above mentioned, the feeder of the press isstarted and the body of the press packed with the material. After arequisite amount of hay or other material has been fed into the press,the clutches 29 and 58 are thrown in and thereupon on the forwardmovement of the plunger, the eccentric disk 25 will be first actuated tocarry the cam track 18 upwardly into engagement with. the roller 17,- sothat as the plunger moves forwardly to press the hay into a bale the'shaft 15 will be given a partial rotation to swing the needles upwardlyand carry the .wire up to the rear side of the bale and then into thetwisters. At the completion of the compressing operation, the mutilatedgear 57 will actuate the rod 52 so as to operate the twisters and effectthe twisting and cutting operations, at the completion of whichthecombined wire holders and drums 63 will be given a lpartialturn to carrythe waste wire forwardly and hold the remaining portion of the wirebetween the bale and the holders until the next bale is formed. Theshaft15 will have a reverse motion imparted to it and carry the needlesdownwardly, and the plunger will move upwardly very much more quicklythan it moved forwardly, so as to giveV more time for the feeder to' actin packing the press prparatory to the formation of the next I-Iavingthus'described the invention, what is claimed as new is:
